The ocean is a vast and complex web of intertwined systems. Chemistry, currents, temperature and nutrients all ebb and flow, each feeding back into the others. A multinational research team, led by UC ...

Carbon dioxide (CO₂) pollution drives climate change, warming the planet and threatening human survival. Plants naturally turn CO₂ into oxygen (O₂) during photosynthesis, but their efficiency is ...

Extensive sea ice covered the world's oceans during the last ice age, which prevented oxygen from penetrating into the deep ocean waters, complicating the relationship between oxygen and carbon.

The Lomagundi-Jatuli event, which occurred more than two billion years ago, followed the Great Oxygenation Event and was marked by a significant change in the isotopic composition of carbon. Its cause ...

As an essential material for the survival and reproduction of almost all aerobic organisms, oxygen is closely related to the formation and development of complex organisms. A recent review provides a ...

Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal ...

Soils store more carbon than the atmosphere and vegetation combined, with soil microorganisms playing the main role. As a ...

Carbon dioxide is being converted into oxygen on Mars thanks to an invention undergoing testing that could lead to the colonization of the red planet. Day and night across the seasons, a ...

This is the fourth article in a series about the mechanics of the natural carbon cycle. Please also see the overview article — Nature-Enhancing Solutions are the Key to Solving the Climate Crisis — ...
